What makes the film so sexy? Fox has one hyphenated word for men everywhere: girl-on-girl.

"There's sort of a hint of, a little bit of a lesbian relationship that happens. There's a girl-on-girl kiss," Fox said of her character, a demonic high school cheerleader, and the girl played by Amanda Seyfried. "Beyond that, before every kill there is a seduction that occurs. The boys have to be seduced to get in close enough to the dead girl in order for her to devour them."

As for horror movies in general, they typically don't appeal to Fox.

"I actually have a very intense fear of the dark. he last horror movie I saw was in 2005, and I was 15 years old. After I saw it, I slept with my mother for two weeks afterwards!"
